How apply functions to csv files

limbs <- c(4, 3)
names(limbs) <- c('One-Eye', 'Peg-Leg')

To apply a barplot to above I use : 

barplot(limbs)

How can I apply the same functionality to a .csv file ? Is there a command I can use to set the limbs & names(limbs) to the limbs,names columns ?

I've read the csv file into memory using : result <- read.csv(result.csv")

The format of the csv is : 

names      limbs
'One-Eye' , 4
'Peg-Leg' , 3

Why not just use the same approach that you use with a normal vector?

> limbs <- result$limbs
> names(limbs) <- result$names
> barplot(limbs)

Or, more directly:

> barplot(result$limbs, names.arg = result$names)
